(C) The velocity of a body projected vertically upwards with an initial velocity $v_{i}$ is given by the equation of motion:$v_{f} = v_{i} - gt$where $g$ is the acceleration due to gravity and $t$ is the time.$1$. Initially,the velocity is positive $(v_{i})$ and decreases linearly with time as the body moves upwards.$2$. At the maximum height,the velocity becomes zero $(v_{f} = 0)$ at time $t = \frac{v_{i}}{g}$.$3$. After reaching the maximum height,the body starts moving downwards,so the velocity becomes negative and increases in magnitude linearly with time.This behavior is represented by a straight line with a constant negative slope $(-g)$ that passes through the positive $v$-axis,crosses the $t$-axis at $t = \frac{v_{i}}{g}$,and continues into the negative $v$-region. Graph $C$ correctly depicts this linear decrease in velocity from a positive value to a negative value.

Among the following,the velocity $(v)$ - time $(t)$ graph representing the motion of a vertically projected body is
